| 摘 要： | 研制了一种温差电效应发电演示热功小车,演示了从热能到电能再到机械能的能量转换过程。该小车以温差发电为电源,利用珀尔帖片、散热片与酒精灯构成核心组件,由酒精灯加热下散热片,下散热片将热量集中到珀尔帖片,珀尔帖片通过上散热片散热,维持珀尔帖片冷热两面有较大温差,输出电能驱动电机旋转,电机带动小车跑动。该小车结构简单,工作原理明晰易懂,运动速度达15 cm/s,演示结果达到了引起人们对温差发电的关注和研究的目的。

| Abstract: | A mini thermo-electric-power demonstration car,which demonstrates the energy conversion from heat energy to electrical energy and then to mechanical energy,was developed to better meet the needs of experiment teaching.In this mini car,a low-heat-sink was heated by an alcohol burner and then delivers the heat to the hot side of a peltier chip(while the cold side was cooled down by a up-heat-sink),which maintains a great temperature difference between the hot and the cold sides of the peltier chip and then outputs the electrical power to drive the motor of the mini car.The demonstration car is simple and efficiency,travelling at a speed of 15 cm/s,which can attract people’s attention to the research of thermo-electric power. |
